kernel BUG at buffer.c:549

[Sokolov Sergei]

Hello!
I have linux kernel 2.4.19-rc1 with xfs enabled.
RedHat 7.2:
Linux version 2.4.19-rc1-xfs (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release))

My xfs partitions locates on /dev/ataraid devices (Promise FastTrak Tx4),
Two mirror on   four disks "Seagate Barracuda IV 80GB".

I have two problems:

1) [root@ws188 linux-2.4.19-rc1-xfs]# mkfs.xfs /dev/ataraid/d1p2
   mkfs.xfs: warning - cannot set blocksize on block device /dev/ataraid/d1p2: Invalid argument

2)When I copying files between partitions, I receive message.
